Freelancer Overview

Profile Overview AI Trainer and bilingual (English–Spanish) evaluator with hands-on experience reviewing and labeling AI training data using structured rubrics. Since 2024, I have worked on evaluating prompt–response pairs for large language models, assessing accuracy, instruction adherence, relevance, and overall outcome quality. My work involves consistent application of detailed guidelines, error classification (including hallucinations and misalignment), and delivery of high-quality annotations at scale in remote, asynchronous environments. I bring a strong quality assurance background from regulated industries, which has strengthened my attention to detail, reliability, and ability to maintain dataset consistency. I am comfortable handling high-volume labeling and evaluation tasks, providing structured qualitative feedback, and supporting iterative model improvement. My bilingual proficiency enables precise semantic and contextual evaluation across English and Spanish content, adding value to multilingual AI training datasets.
